Royal Ascot: So You Think a heavy favorite in Prince of Wales's

So You Think, the 6-year-old New Zealand-bred horse, has won nine Group 1 races in his career in locations as diverse as Australia, England, and Ireland.

Later this year, So You Think will begin stud duty in Australia. Until then, he has time to add to his record. On Wednesday, he will be a heavy favorite to win the Group 1 Prince of Wales’s Stakes over 1 1/4 miles on turf at Royal Ascot.

Trained by Aidan O’Brien, So You Think has padded his record this year, with a six-length win in the Group 1 Tattersalls Gold Cup at The Curragh in May.

The win ended a four-race losing streak, which came in the some of the world’s greatest races – a fourth in the Prix de l’Arc de Triomphe in Paris, a second in the Champion Stakes at Ascot, a sixth-place finish in the Breeders’ Cup Classic at Churchill Downs, and a fourth in the Dubai World Cup at Meydan in March.

So You Think will be ridden by O’Brien’s son Joseph, and is part of a field of 11 in the $785,000 Prince of Wales’s Stakes. Wednesday’s race will be So You Think’s third start at Ascot; he was second as a heavy favorite to Rewilding in the 2011 Prince of Wales’s Stakes.

Owned by a partnership, So You Think’s main rival is Carlton House, the winner of the Group 3 Brigadier Gerard Stakes at Sandown Park on May 31. Owned by The Queen of England and trained by Sir Michael Stoute, Carlton House was third in the English Derby and fourth in the Irish Derby last year. He did not start in the second half of 2011. The Brigadier Gerard Stakes was Carlton House’s first start in 11 months.

There is an American presence in the race in Big Blue Kitten, who was second in the Grade 3 Ben Ali Stakes at Keeneland in April. Owned by Kenneth and Sarah Ramsey and trained by Chad Brown, Big Blue Kitten will be ridden by Johnny Murtagh and was a 50-1 outsider as of Monday.

The six-race Royal Ascot program includes two Group 2 races – the Windsor Forest Stakes for fillies and mares over a mile and the Queen Mary Stakes for 2-year-old fillies over five furlongs.

Emulous, the winner of the Group 1 Matron Stakes in Ireland last year, will be favored in the Windsor Forest.

The Queen Mary Stakes drew a field of 27, including the unbeaten Jadanna who will be ridden by Frankie Dettori.
